Abstract (en)

[origin: WO2016156882A1] A method of operation of a scintillator detector comprising a scintillator and a photodetector is described, together with a device embodying the method. The method comprises the steps of: periodically producing a light pulse; impinging at least some of the light from a successive plurality of such light pulses onto a light- receptive part of the photodetector; measuring the electrical response of the photodetector; processing the electrical response of the photodetector to determine a pulse height and a variance of pulse height; numerically processing the pulse height and variance of pulse height so determined to obtain at least a first data item characteristic of the response of the photodetector. The method additionally or alternatively comprises the steps of: periodically producing a light pulse including light in the ultraviolet spectrum; impinging at least some of the UV light from a successive plurality of such light pulses onto a light-receptive part of the scintillator; inducing photon emission in the scintillator in the visible spectrum; measuring the electrical response of the scintillator; processing the electrical response of the scintillator to obtain at least a data item characteristic of the response of the scintillator; and optionally verifying the electrical response of the scintillator by comparing at least the said data item against a predetermined reference response; and optionally additionally or alternatively outputting a control signal to the photodetector, which signal is modified in part responsive at least to the value of the said data item.
